Q of the door sheets fit and to which said To all whom it may concern:

Be it" known that I, WALTER P. MURPHY,

;a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Car-Doors, of which the following is a'specification.

In the drawings: Figure 1 is a front elevation of a car door embodyingmy invention applied to a car, the car being broken away. Fig. 2 is avertical sectional view on the line 22, Fig. 1. Fig. 3 is an end view ofthe door detached. Fig. dis a top plan view of the door, partly brokenaway. Fig.

5 is an enlarged detail sectional view on the line 5-5, Fig. 1, lookingin the direction of the arrow. Fig. 6 is an enlarged detail perspectiveview of one of the side marginal binding members. Fig. 7 is an enlargeddetail sectional view of the joint between the corrugated sheets,

The object of my invention is to provide 4 a simple, cheap, butsubstantial car door of such construction that it can be easily andquickly repaired and with this and other objects in view my inventionconsistsv of the parts and. combination of parts as will be hereinafterpointed out.

The cardoor is made up of a plurality of corrugated sheets, 1, theadjacent marginal edges of which overlap and are interlocked as moreclearly shown in Fig. 7 and.

. are secured together on eachside of a full corrugation by rugation thejoints between the sheets serve to reinforce the structure. It is ofcourse obvious that I may spot weld'the sheets instead of riveting.

3 are side marginal binders for the door which is made of angle iron,one leg of which is straight agalnst which the side marginal edges ofthe sheets 1 abut, whereby the ends of the corrugations are closed, theedge of this leg fitting snugly against the side of the car when in theclosed position thus making a weather-proof joint therebetween. Theother leg of the binder bars 3 is corrugated over which the corrugationsSpecification of Letters Patent.

sheets are riveted by means of the rivets- 4:- The rivets are passedthrough the crown of the corrugation.

5 are. gusset plates riveted to the door sheets at the top corners ofthe door to which suitable door hangers 6 are riveted so as todistribute theweight of the'door over a larger area of the sheet thanwould be possible if the hanger was fastened vto the sheet direct. Thegusset plates also serve to stiffen the door. 7

At the bottom of the door I secure gusset plates 7,-the lower portion ofeach of which depends below the lower edge of the door proper as at 8and engages the door guides 9 and serves to hold the door against theside of the car so asto form joint therebetween when the door is in itsclosed position. The rivets 10 securing the gusset plates to the doorsheets pass through the crown of a corrugation. j

11 is the car sill, 12 the car floor, and 13 is a bolt securing the doorguide to the car.

What I claim is 1. A metal car door comprising a plurality of corrugatedsheets the adjacent marginal edges of which overlap wherebya corrugationof one sheet interlocks with a corrugation of the next adjacent sheet,means securin the adjacent sheets together through-the sides of theoverlapped corrusecured to the sides of the doors, each angle bar havingone leg corrugated to fit the corrugations of the sheets of the door.
